2. Connect the remaining end of the grounding cable to a proper earth ground, such as the rack in which the switch is

does not drape where people could trip over it.

Connect Power to the Switch

The QFX5220-128C is shipped from the factory with four power supplies. Each power supply is a hot-removable and
hot-insertable field-replaceable unit (FRU) when the second power supply is installed and running. You can install a
replacement power supply in either of the two slots next to the fan modules without powering off the switch or disrupting
the switching function.
To connect AC power to a QFX5220-128C:
1. Attach the grounding strap to your bare wrist and to a site ESD point.
2. Ensure that the power supplies are fully inserted in the chassis and the latches are secure.
3. Locate the power cords shipped with the switch; the cords have plugs appropriate for your geographical location.
For each power supply:
a. Ensure the loop on the power cord retainer is open and there is enough space to insert the power cord coupler into
the inlet. If the loop is closed, press the small tab on the retainer to loosen the loop.
b. Thread the power cord coupler through the power cord retainer loop.
